Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31554546, here are decompositions:

5 + 31554541 = 31554546
7 + 31554539 = 31554546
19 + 31554527 = 31554546
29 + 31554517 = 31554546
53 + 31554493 = 31554546
73 + 31554473 = 31554546
83 + 31554463 = 31554546
97 + 31554449 = 31554546

Showing the first eight; more decompositions exist.
